Some general FPCA methods are implemented in R packages fda
[1]} and refund [2]}.
The multivariate FPCA approach of [3]} is implemented in package MFPCA
[4]};
the PACE algorithm of [5]} in fdapace
[6]}.
The methods outlined in [7]}
are available for the binary curves setting in gfpca [8]},
where the mixed regression in the two-step approach is estimated with package gamm4
[9]}.
Our accompanying package registr [10]} implements the Gaussian
and binary curve
GFPCA of [11]} as well as the two-step approach of [7]}
for various exponential family distributions.
